Abstract

Structural and aerodynamic characteristics for the two resonant type elastic flapping wings are experimentally and numerically investigated. The numerical simulation of aeroelastic response for the two wings is conducted by the 3D Navier-stokes code considering the modal analysis calculated by FEM. The thrust performance and the vibrational mode are in good agreement between the experimental and numerical results. The aerodynamic responses obtained by the numerical simulation indicate that the two wing models show the preferable wing kinematics with respect to the feathering amplitude and the phase difference between the flapping and feathering motions. On the basis of the numerical estimation, we have selected the appropriate driving motor for the resonant type flapping wing and designed and developed a new prototype of the flapping Micro Air Vehicle, which has four resonant type flapping wings with four driving motors. In the tethered flight test, the prototype succeeded in lifting the body with the weight of 80.8 g except a buttery and motor controller.
